She said she and her husband Paul, 39, believed the primary school pupil from Leadgate, County Durham, had drunk a mixture of vodka, wine and orange juice after being encouraged by two friends, also aged nine.

It is thought Rhiannon drank around half a pint of the cocktail, which was made from alcohol found in a cupboard at her friend's house.

It comes a month after Bradley Eames, 20, from Nottingham was found dead after he filmed himself downing almost two pints of gin mixed with tea bags.

He was the third youngster to die after taking part in the deadly NekNominate craze.

The game involves players filming themselves downing drinks and posting the videos, daring each other to outdo the stunts with increasingly large amounts of alcohol or in dangerous situations.

Figures from the Office for National Statistics released last month revealed deaths from accidental alcohol poisoning in England and Wales have rocketed by more than 200 per cent in the last ten years.

Mrs Scully believes her daughter's drinking dare was filmed on a mobile phone but the footage was deleted shortly after.

She said: "We found out in the ambulance that it was a NekNomination. Rhiannon said 'them stupid NekNominations'."

She added: "I wouldn't like to see this happen to any other child and I wouldn't wish the feeling I felt as a parent on my worst enemy.
